SASH-LOCK.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed January 10, 1913. Serial No. 741,304.

To all whom it may concern:

Be it known that I, HENRY J. STANG, a citizen of the United States,residing at Bison, in the county of Bush and State of Kansas, haveinvented certain new and useful Improvements in Sash-Locks, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to new and useful improvements in locks and moreparticularly to sash locks, the object of the invention being to providea sash lock wherein the locking bolt is normally retained in a lockedposition and also to provide means whereby the bolt can be quickly andeasily thrown to an unlocked position.

Another object of the invention is to provide a casing of novelconstruction in which the various parts of the locking mechanism areinclosed.

A further object of the invention is to provide a lock of the abovecharacter which will possess advantages in points of efliciency anddurability, is inexpensive of manufacture and at the same time is simplein con struction and operation.

With the above and other objects in view, the invention consists in thenovel features of construction and the combination and arrangement ofparts to be hereinafter more fully described, pointed out in the claimand shown in the accompanying drawings, in which Figure 1 is a view intop plan of a lock constructed in accordance with my invention. Fig. 2is a top plan View, the cover being removed. Fig. 3 is a front view ofthe keeper member and Fig. 4 is a side elevation of the look.

In the construction of my improved look, I provide a casing 1 which ispreferably rectangular in shape and having one side open as shown at 2.The open side 2 is closed by means of a suitable cover 3 having acentrally arranged tongue 4 formed at one side thereof and adapted to bebent rearwardly and engage over the side of the casing 1 to securelyhold one side of the cover in position. The other side of the cover isprovided with the spaced tongues 55 which are adapted to be bentdownwardly over the side of the casing to securely retain this side ofthe cover in position. Thus it will be apparent that by means of thetongues 4 and 5 the cover is securely held in place and the same may bereadily removed by bendmg outwardly upon the tongue, it being understoodthat the cover is made of suitable metal whereby the tongues will besupplied with sufiicient resiliency to allow of the.

bendingof the same. 1 I

Arranged transversely within the casing for sliding movement is thelocking bolt 6 one end of which is adapted to project through an opening7 formed in one of the side walls of the casing and engaged beneath thekeeper member 8. The material which is cut from the opening 7 is dividedin the center and each half bent inwardly into the casing to form spacedflanges 7 adapted to be disposed upon opposite sides of the bolt 6 andbrace the same against lateral movement. The bolt 6 is nor-' mallyretained in a locked position by means of the leaf spring 9 which isbent upon itself and having its ends arranged in resilient spacedrelation so that one end thereof engages the inner end of the bolt andthe other end engages the rear side wall of the casing to resilientlyhold the locking bolt in its normal position.

Mounted for rotary movement within the casing is a drum 10, one end ofwhich projects outwardly through the casing to form a suitablefingerhold 11 whereby the drum may be readily turned. Pivotally securedat one end to the locking bolt adjacent the inner end thereof is a rod12, the other end,

of said rod being slidably directed through the drum 10 so that when thedrum is rotated by means of the finger hold 11, the bolt will bewithdrawn from its locked position as shown in Fig. 4, placing thespring 9 under tension. Thus as the drum is released, the tension of thespring 9 will return'the locking bolt to its locked position.

The locking bolt 6 is provided with an elongated slot 13 in which isdisposed a pin 14, said pin being carried by the casing and adapted tolimit the outward sliding movement of the bolt when thrown to its lockedposition. 7

From the above description taken in connection with the accompanyingdrawings, it will be readily apparent'that I have provided a simple anddurable sash lock whereby the operating mechanism thereof is'disposedwithin a casing of novel construction and it will also be apparent thatI have provided a lock which is composed of comparatively few parts, issimple in construction and operation and can be manufactured atcomparatively low cost.

/Vhile I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope of the appended claim.

What I claim is A sash lock including a casing provided with an opening,a bolt slidably supported within the casing and adapted to be directedthrough the opening thereof, a rod having one end pivotally connected tothe bolt, a drum rotatably mounted within the casing and through whichthe free extremity of the rod is slidably directed, said drum beingprovided with means whereby it may be rotated.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses.
